Test Tuesday: Waterproof Ink

In this Test Tuesday we are working with waterproof ink. I am using Higgins brand black waterproof drawing ink. In an earlier Test Tuesday we looked at Higgins Non-Waterproof ink, which can be found here. I will be making some comparisons between the two inks, so I urge you to read the previous article first.

For each of the samples I used a brush to create a line and used the dropper attached to the lid to apply a drop of ink. I held the tip of the dropper approximately an inch and a half from the foam board surface.

The standard Readi-Board samples work well with the ink. The drop on the red and blue samples bled slightly, the blue more so than the red. In comparison to the non-waterproof ink, the bleeding was minimal.

On all the Adams Premium samples the ink made a nice, dark mark. There was a small amount of feathering around the drop of ink on the white Adams Premium, but this was the only noteworthy difference across the samples.

The line on the No Paper sample didn’t have the same peculiar texture as the non-waterproof ink. The waterproof ink created a line with flat, even coverage. Both the Readi-Erase and Readi Water Resistant samples had clear, dark marks. The results were much different than the non-waterproof. The ink does not flake off of the Readi-Erase. I am able to scrape some of the ink from the Water Resistant sample, but it does still leave a dark stain behind.

The brush mark on the Readi-Grid was most similar to the standard Readi-Board samples. The grid lines are more visible due to the ink. Interestingly it is because the ink darkened the grid lines, whereas on our non-waterproof sample the gridlines resisted the ink, leaving them lighter than the surrounding paper.
